Global Lake Ecological Observatory Network: Long term chloride concentration from 529 lakes and reservoirs around North America and Europe: 1940-2016

This dataset compiles long term chloride concentration data from 529 freshwater lakes
and reservoirs in Europe and North America. All lakes in the dataset had greater than or
equal to ten years of data. For each lake the following landscape and climate metrics were
calculated: mean annual precipitation, mean monthly air temperatures, road density and
impervious surface in 100 to 1500 m buffer zones, sea salt deposition. The dataset includes
three files: 1) Descriptive data of lake sites (physical lake metrics, climate, land-cover
characteristics), 2) Chloride time-series, and 3) GIS shapefiles.

本数据集整合了欧洲与北美洲共计529个淡水湖泊及水库的长期氯离子浓度监测数据。数据集内所有湖泊的监测时长均不少于10年。针对每个湖泊，本数据集计算了以下景观与气候指标：年平均降水量、月平均气温、100米至1500米缓冲区内的道路密度与不透水面占比，以及海盐沉降量。本数据集包含三类文件：1）湖泊点位描述性数据（涵盖湖泊物理指标、气候与土地覆盖特征）；2）氯离子浓度时间序列数据；3）GIS形状文件（shapefiles）。
